How to Conduct a Factory Acceptance Test (FAT) for Machinery Equipment in China

When sourcing machinery and equipment from China, the focus of a Factory Acceptance Test (FAT) is not just simply confirming that "the machine can start." Instead, it is about verifying whether the equipment meets the agreed-upon status in accordance with the order and technical requirements. Formal acceptance is best completed before packaging and container loading, giving buyers the opportunity to identify issues related to configuration, functions, capacity, accessories, or documentation, and to require suppliers to complete rectifications before the equipment leaves China.

What is the Difference Between FAT and a Standard Pre-Shipment Inspection (PSI)?

A standard PSI focuses more on quantity, appearance, packaging, and order consistency, whereas a machinery FAT leans more toward the operational and technical status of the equipment itself.

For example, a production machine may look flawless in appearance, but its actual operating speed might fall short of the agreed production capacity, the control system might lack a specific function, or the raw materials used during testing might differ entirely from the buyer's real production conditions. Such issues are difficult to uncover through a visual inspection alone.

Therefore, pre-shipment inspections for high-value machinery typically require incorporating FAT as a core component rather than merely checking wooden crates and machine exteriors.

What Should Buyers Prepare Before Acceptance?

The most important step is to recompile the technical conditions agreed upon during procurement.

This can include:

• Final confirmed equipment model and configuration
• Technical parameters and target production capacity
• Voltage, frequency, and electrical requirements
• Raw materials or test products
• Functional and control requirements
• Mold, auxiliary machine, and accessory lists
• Wear parts and spare parts requirements
• Technical documents and user manuals

If the supplier modified the configuration during the quotation process, the final confirmed version shall prevail.

Without clear acceptance standards, an FAT easily turns into a product demonstration by the supplier rather than a genuine verification of the order by the buyer.

What Should Be Inspected During Equipment Testing?

First, the equipment must be operated under normal production conditions rather than just idling for a few minutes.

If conditions permit, it is best to use materials or products close to the buyer's actual production for testing, observing whether the equipment runs stably, operates normally, and whether the finished products meet the requirements.

For equipment with clear capacity commitments, actual output over a certain period should be recorded rather than relying solely on the supplier's theoretical speed claims.

For automated equipment, attention must also be paid to whether sensors, alarms, emergency stops, control interfaces, and different working modes function properly.

If the equipment includes multiple main and auxiliary machines, it should also be confirmed that the entire system connects and integrates correctly, rather than considering the acceptance complete just because each individual unit starts up separately.

Configurations Must Match the Order Item by Item

Price differences in machinery and equipment often stem from configuration variations. Therefore, during an FAT, you cannot simply check whether the machine is physically built.

It is necessary to verify whether the motors, PLCs, frequency converters, control systems, pumps, hydraulic components, core bearings, or other critical parts match the final order.

If the buyer specified a brand or model, it is best to take photos of the nameplates and key components.

Critical components that are easily replaced later or hidden inside the equipment can also be highlighted during the acceptance stage.

This helps prevent a scenario where one configuration is discussed during quotation, but a different configuration is ultimately delivered.

Why Are Random Accessories and Technical Documents Easily Overlooked?

Once the main equipment is completed, suppliers can easily overlook "small items," which may prove crucial once the equipment arrives overseas.

Examples include tools, molds, wear parts, backup sensors, electrical components, installation attachments, and operation manuals. If a single critical component is missing, the equipment may fail to be installed or commissioned properly upon arrival.

An FAT stage should jointly verify random accessories and documentation.

For complex equipment, buyers can also request suppliers to prepare electrical diagrams, spare parts lists, operating instructions, maintenance requirements, and wear-part models to facilitate subsequent repairs.

What Records Should Be Obtained from an FAT?

A valuable FAT should not conclude with just a statement that "the equipment passed testing."

Buyers are advised to obtain reviewable and verifiable evidence, such as:

• Overall equipment and nameplate photos
• Key configuration photos
• Continuous operation videos
• Test products or results
• Actual parameter logs
• Random accessory photos
• Defect and rectification logs

If abnormalities are discovered during testing, records should detail what the issue was, how the supplier handled it, and whether re-testing was required.

Such documentation will have reference value for future overseas installation, commissioning, or dispute resolution.

Does Passing FAT Mean Zero Equipment Risk?

That cannot be assumed.

An FAT only mitigates risks that can be identified before the equipment leaves the factory. It cannot guarantee zero damage during transit, nor can it replace on-site installation and final commissioning overseas.

If the equipment requires dismantling for packaging, container loading checks must still confirm proper securing, moisture protection, crating, and component labeling.

After arriving at the overseas factory, installation, electrical connection, commissioning, and trial production must still be completed according to site conditions.

Therefore, FAT should be understood as a crucial control node within the equipment delivery process, rather than a guarantee that "all risks drop to zero once passed."

How Easysail China Assists with Machinery FATs

Easysail China can assist overseas buyers based on their orders, technical agreements, and equipment configurations to establish FAT inspection priorities prior to shipment. We visit supplier sites to record equipment testing, key configurations, random accessories, and technical documentation.

If testing reveals that equipment functions, configurations, or accessories do not match the order, we consolidate these issues and report them back to the buyer, while continuing to follow up on supplier rectifications and necessary re-inspections.

Once the FAT is successfully completed, we can seamlessly transition into packaging inspection and container loading supervision, ensuring that the approved equipment and accessories are correctly loaded into containers.

If you are currently sourcing machinery, production equipment, or complete production lines from China, feel free to send your equipment quotations, technical parameters, configuration lists, and testing requirements to Easysail. We can help transform your supplier's routine "equipment test" into a factory acceptance inspection genuinely executed from the buyer's perspective.
